Un'rrnn s'rag'rns Parente @Prion IMPROVEMENT IN LAMe-cHiMNEvs.

Specification forming part of Letters Patent No. 125,090, dated March 26,1872.

To all whom 'it may concern:

Be it known that I, WILLIAM SEDcrwrcK, of the city of Poughkeepsie, in the county of Dutchess and State ot' New York,have invented certain Improvements in Lamp-Chimneys, ot' which the following is a specification, ret'- erence being had to the accompanying' drawing. 4 i

My invention consists in a lamp-chimney of novel construction, which admits of the lamp being carried in the wind and rain, permits theA ilame to be lighted and extinguished without removing the chi lmney, and also serves as a reector, so that an ordinary lamp provided with one ot' these chimneys will answer all the purposes ot' a lantern.

Figure l is a front elevation of my chimney 5 Fig. 2, a cross-section ot' the same on the line w ot' Fig. l; and Fig. 3, a rear view of the lower end.

In constructing my chimney I first provide I a sheet-metal tube orbody, A, otl suitable size and form to iit upon 'an ordinary lamp in place of the usual chimney, and through the side ot'- the same cut a large opening, as shown, so as to leave only a narrow strip of metal, a, to connect the two ends. I next turn the metal inward along the sides of the opening, so as to form lips or iianges c, as shown in Fig. 2, and then insert in the body a sheet ot' mica, B, so as to close the opening in the side of the same, slipping the edges ot' the mica under the lips e, so that they serve to hold it in position. In the back ot' the body I make an opening, c, through which the alne lnay be lighted or eX- tinguished without removing the chimney. I also pivot to the body a swinging door or cover, d, for the purpose of closing the hole c, the

back of the door being roughened, as shown in Fig. 3, so that matches may be lighted upon it. The inside of the metal body back of the dame I polish, so as to serve as a reiector to throw the rays ot' light out through the mica front. To the top of the body I attach a cap or cover, D, to exclude the wind and rain, the cover being provided with and supported by three spring-arms, i, which bear against the inside ol' the body. These arms permit the cap to be raised and depressed as may be necessary, and to be removed when desired.

An ordinary lamp provided with this chimney may be carried out of doors in all weather without danger of the light being extinguished or the chimney broken, and may be used in all places with the same sat'ety from accidental fire, as with an ordinary lantern.

When used indoors the cap may be removed or not, as desired. Instead of using the removable cap a rigid conical top may be used. In case the mica becomes soiled or broken it may be slipped out and cleaned, or a new piece substituted for it. The body may obviously be made of any form and size desired, or the body made ot' one size or shape and the base ot' another, so as to it on the lamp.

Having thus described my invention, what I claim isrlhe herein-described chimney, consisting of the metal body A, provided with the mica front B, cap D, opening c, and door ci, all constructed and arranged substantially as described.
